Hello,
Have just noticed this thread. HHs comment is in my opinion unwise, whilst a percentage of people are repatriated from Spain commercially the problem is that if you need an air ambulance it will cost from somewhere like southern Spain up to £30,000, from NZ you are looking at the best part of £250,000 for an air ambulance. So you need good insurance and do not forget to declare everything and I mean everything to the insurance company.
Because of your age you may have to pay an awful lot or insurance and usually it will only cover you for 45 days continuously outside the country.
Remember, because you are in good shape today you don't know what next week brings such as a chest infection or just tripping over a pavement and breaking a hip.
